Jumbo OLED Fun

Jumbo OLED next to a Floppy Emu

A few days back, a discussion on the Apple II Facebook group asked about large format Floppy Emu displays for people with vision difficulties. Here’s a 2.42 inch OLED that’s a simple drop-in replacement for the OLED in Floppy Emu Model C. With more than 3x the screen area of the standard OLED, that’s a big increase in display size!

This particular OLED was $17.99 and can be purchased from AliExpress. The only minor issue is that the rightmost column of pixels appears on the left side of the display – some sort of off-by-one error.

  4. Is there a firmware fix for the ‘off by one’ pixel issue? perhaps a ‘big screen firmware’? that would be great. Thanks!

  5. There is no simple “fix”, but I sent you a one-off firmware version that draws correctly on the jumbo LED shown here. It won’t work on the normal size OLED. Displays with different sizes may also use different controller chips, which require different commands and addressing to update the display. The display is a write-only device, so unfortunately there’s no way to query it to see what controller is present.

  10. I just bought the Floppy Emu Mod C Delux BUndle and have been getting familiar with using it. I have a comment/request echoing one in another post dated as a couple of years ago. It is about the challenges of the small screen size for not so young (or perfect) eyes. Is there anything new/recent in terms of a screen mod available? I am not a soldering techie but I can handle plug and play 🙂

    Tnx

    • Support for the “jumbo” LED was made permanent in 2022 – it’s an option in the settings menu. You can find these displays on eBay or Amazon and they just plug in, replacing the original display.

  11. I also purchased a wDrive and it has an option to show that device’s menu on the monitor. Haven’t tested that yet but Chris Torrence’s video shows it and it looks good. Could that be an option for the Floppy Emu?

  12. Hi. Tnx. In looking at Amazon and eBay I see there are 4-pin and 7-pin connection types available and there are 12C and SPI whaatever those are. I see your resonse above confirming that FE uses the SPI. Which of the pin connection configs is required? My FE in inside the acrylic case and I don’t really want to dismantle until I decide. Tnx Much. (I could see the specs online)

    • In the body of the post, you can find a link to the exact OLED that I tested with and review the specs. It’s a 7-pin SPI. The pins are VSS, VDD, SCLK, SDA, RES, DC, CS. This seems to be a standard and I haven’t encountered any similar OLEDs with a different pin layout, but it still pays to double-check.
